It initially appeared that Daniels wouldn't participate in the team's afternoon practice. He spent the beginning of the session in the weight room then trotted out to the field without pads and watched the end of individual drills. He headed to the locker room when team drills began which was also when practice was closed to the media.

But the Sacramento Bee reported that Daniels did eventually suit up and participate in practice.

The rookie emerged as a candidate for the primary backup spot to Colin Kaepernick after leading a game-winning touchdown drive against Kansas City on Friday the 49ers' first touchdown drive of the exhibition season."It was an encouraging performance" Harbaugh said. "If someone does a good job you give them a little more."

McCoy and Tolzien have been the leading candidates to serve as Kaepernick's backup but neither has impressed during the first two exhibition games. Tolzien has completed 18 of 34 passes for 188 yards and an interception. McCoy is 6 of 13 for 76 yards and two picks.

Meanwhile Daniels guided San Francisco on a 13-play 90-yard drive that resulted in a 14-yard touchdown pass to Chuck Jacobs to provide the difference in a 15-13 win over the Chiefs. He completed 6 of 9 passes for 72 yards in his NFL quarterback debut.
